Planting Tips for Clay Soil Success

1. Amend with Organic Matter:
Clay holds nutrients but drains poorly. When planting, dig a hole 2–3 times the width of the root ball and mix in 25–30% organic compost or well-rotted leaf mold with the native clay. Avoid replacing all the native soil—this encourages roots to stay confined.
2. Elevate If Needed:
If the soil is especially compacted or prone to waterlogging, plant trees slightly higher than the surrounding grade (1–2 inches above ground level) and slope the soil away from the trunk.
3. Add Small Rocks: It will help the roots from sitting in water too long if an inch or two of small pebbles are added before adding plant and soil.

Watering Habits in Clay Soils

Clay retains moisture longer, so it’s important not to overwater. During the first growing season:
• Water deeply once or twice per week, allowing time for the top few inches to dry out between sessions. Overwatering can lead to root rot.
• Check the soil 3–4 inches down before watering—if it’s still damp, hold off.

Once established, most clay-tolerant trees will need little supplemental water unless drought conditions persist.

General Care for Clay-Loving Trees

Mulch Matters: Apply a 2–3-inch layer of mulch (keep it away from the trunk) to moderate temperature swings and improve drainage over time.

Fertilize Lightly: Apply a slow-release fertilizer in early spring if growth seems sluggish, but clay soil often contains adequate nutrients.

Prune with Purpose: Shape young trees to develop strong structure and remove any dead or damaged limbs in late winter or early spring.
